I installed mageia 4.1 via the LiveCD and it works OK on my (older) Vaio laptop (Nvidia) until I update it. As soon as new kernels go on the video stops working and no amount of use of XFdrake fixes it. It says there's the propriatory driver and asks if I want to use it (yes) but after installation it kills X such that it is no longer usable. I once made the awful mistake of trying to use noveau instead until I could get nvidia working but that rendered the screen unusable as most windows didn't "paint" except as brief vague outlines of windows. The taskbar was invisible too so I was stuck. I just now tried reinstalling from scratch and, again, it works (with nvidia driver) initially but as soon as I make the mistake of updating the system, I lose X.
Part of the problem is I am unable to make any sense of the MANY kernels. There's desktop kernels and desktop586 kernels that appear to be identical and redundant. I try to install a dkms-nvidia (or virtualbox) and the system insists on also installing 3 or 4 other kernels to meet dependencies! WTF?
